Linux上怎么配置Nginx+Ruby on Rails+MySQL教程,用到了RVM,此种服务器搭建配置极力推荐。
安装 RVM
通常用 RVM 或 rbenv 来安装 Ruby,这里选用 RVM。
1
|
$ curl -sSL https: //get .rvm.io | bash
-s stable |
载入 RVM :
1
2
3
|
$ source
/home/libuchao/ .rvm /scripts/rvm $ rvm - v rvm 1.25.12 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com> ...... |
再执行以下命令:
1
2
3
|
$ type
rvm rvm is a function ...... |
说明 RVM 安装正确。
安装 Ruby
用 RVM 安装 Ruby
1

3
4
|
$ rvm install
2.1.0 $ rvm use 2.1.0 --default $ ruby - v ruby 2.1.0p0 |
国内服务器推荐替换 RubyGems 的到淘宝镜像
1
2
|
$ gem sources -r https: //rubygems .org/ $ gem sources -a http: //ruby .taobao.org/ |
否则安装 Gem 可能会非常非常慢。
安装 Rails
其实 Rails 也是一个 Gem
1
2
3
4
|
$ gem install
rails --no-ri --no-rdoc -V ...... $ rails - v Rails 4.0.2 |
至此,Rails 环境已经安装完成。
安装 MySQL
安装 Mysql 及相应的库文件:
1
|
$ sudo
apt-get install
mysql-server libmysqlclient-dev |
然后进行一些安装方面的设置:
1
|
$ /usr/bin/mysql_secure_installation |
创建相应的数据库,并为它新建一个权限小一些的用户:
1
2
3
4
|
mysql> CREATE
DATABASE
blix_production; mysql> GRANT
ALL
PRIVILEGES
ON
blix_production.* TO
blix@localhost IDENTIFIED BY
"123456" ; mysql> flush privileges ; mysql> exit |
导入数据:
1
|
$ mysql -u blix -p blix_production < database.sql |
安装 Nginx
Nginx 专门处理静态请求,并作为 Unicorn 的反向代理
编辑 /etc/apt/sources.list,末尾处添加以下两行
1
2
|
deb http://nginx.org/packages/ubuntu/ precise nginx deb-src http://nginx.org/packages/ubuntu/ precise nginx |
添加 Nginx 签名
1
2
|
$ wget http: //nginx .org /keys/nginx_signing .key $ sudo
apt-key add nginx_signing.key |
安装 Nginx
1
2
|
$ sudo
apt-get update $ sudo
apt-get install
nginx |
安装完成后可以在浏览器中输入 http://server-ipaddress 查看是否安装正确。
配置 Unicorn
首先编译一下静态文件:
1
2
|
$ RAILS_ENV=production rake assets:clean $ RAILS_ENV=production rake assets:precompile |
Unicorn 配置参考:

#!/bin/sh set
-e # Example init script, this can be used with nginx, too, # since nginx and unicorn accept the same signals # Feel free to change any of the following variables for your app: TIMEOUT=${TIMEOUT-60} APP_ROOT= /home/libuchao/blix APP_USER=libuchao PID=$APP_ROOT /tmp/pids/unicorn .pid CMD= "unicorn_rails -D -E production -c $APP_ROOT/config/unicorn.rb" action= "$1" set

$APP_ROOT || exit
1 sig () { test
-s "$PID"
&& kill
-$1 ` cat
$PID` } oldsig () { test
-s $old_pid && kill
-$1 ` cat
$old_pid` } case
$action in start) sig 0 && echo
>&2 "Already running"
&& exit
0 su
-c "$CMD"
- $APP_USER ;; stop) sig QUIT && exit
0 echo
>&2 "Not running" ;; force-stop) sig TERM && exit
0 echo
>&2 "Not running" ;; restart|reload) sig HUP && echo
reloaded OK && exit
0 echo
>&2 "Couldn't reload, starting '$CMD' instead" su
-c "$CMD"
- $APP_USER ;; upgrade) if
sig USR2 && sleep
2 && sig 0 && oldsig QUIT then n=$TIMEOUT while
test
-s $old_pid && test
$n - ge
0 do printf
'.'
&& sleep
1 && n=$(( $n - 1 )) done echo if
test
$n -lt 0 && test
-s $old_pid then echo
>&2 "$old_pid still exists after $TIMEOUT seconds" exit
1 fi exit
0 fi echo
>&2 "Couldn't upgrade, starting '$CMD' instead" su
-c "$CMD"
- $APP_USER ;; reopen-logs) sig USR1 ;; *) echo
>&2 "Usage: $0 <start|stop|restart|upgrade|force-stop|reopen-logs>" exit
1 ;; esac |
将这个 shell 在/etc/init.d/下做一个软连接,并使其开机自启动:
1

|
$ chmod
+x /home/libuchao/blix/config/unicorn_init .sh $ sudo
ln
-s /home/libuchao/blix/config/unicorn_init .sh /etc/init .d /unicorn $ sudo
update-rc.d unicorn defaults |
启动 Unicorn:
1
|
$ service unicorn start |
在浏览器中输入 http://server_ipaddress:8080 查看效果。

此时应该可以通过域名直接访问了。
